| Abstract: | ased on the practical examples and by using the hydraulic pressure-time curve,the cruetal stressis estimated and the computation'equations for the minimum horizontal main stress.maximum horizontal mainstress and longitudinal stress are given,the direction of the crustal stress in Ausal is analysed alld the relation ofthe three main stresses is discussed.It pointsout a pair of main co-yoke fractutes axlst .which means the primarydirection in this area is north-east.The determination of the horizontal welll S spot is analysed by using themethodal and equations mentioned in literatures and combining with the'direction of the fractures in this area.Acomputed result of a horizontal welll S optimum azimuth is given in this paper/Ansai.North shaallxi |
